For all of Kings talk about 9/11 and Homeland Security, he joined with fellow republicans in OPPOSING the creation of an independent 9/11 Commission.
After the 9/11 Commission was formed, King joined with Bush in OPPOSING Bush Administration officials from having to testify under oath.
King didn't want Condi Rice under oath.
King didn't want Bush or Cheney under oath.
King saw no reason to get to the bottom of why the attacks on 9/11 happend other than terrorists attacked us.
THAT is Kings legacy.
